Abstract: ABSTRACT OF THE DISCLOSURE A process for the manufacture of polyamides, polyam-ide-imides and polyimides which process comprises pre-paring a salt of an aliphatic or aromatic diamine or a mixture of these and di, tri or tetracarboxylic acid or mixture of these or their corresponding anhydride by reacting both feedstocks at a temperature of about 300 to 500°F in a solvent medium provided the water content of the resulting solution is below 25% water by weight the resulting salt solution is subjected to a pressure of about 1500-3000 psig and is then passed through a preheat zone where the temperature is increased to about 625°F, the total residence time is kept at about 25 to about 50 seconds.  The reactants are flashed through a control valve or nozzle to give an aerosol mist at a pressure of about 0-400 psig, the polymerization is further carried out in a flash reactor with a high heat flux and with wall temperatures of about 600°F to about 1000°F and melt temperatures of about 500°F to about 750°F, the total polymer residence time in the reactor is kept about 0.1 to about 20 seconds.  The novel compositions are useful for engineering resins.  Also a process for the manufac-ture of polyesters and polyarylates by the process dis-closed above, except that instead of a salt, a prepolymer is prepared and the reactants for polyesters are dicar-boxylic acids and glycols, for polycarbonates, diphenols and phosgene, for polyarylates, diphenols and dicarbox-ylic acids and for polyesterarylates, dicarboxylic acids and phosgene.

Abstract: ABSTRACT OF THE DISCLOSURE     A data base system uses a self-descriptive index key format having variable length data fields so that the data base system manipulation is independent of the type and arrangement of the data being stored and retrieved. The data is characterized by three index variables which represent the data table, the record in that table, and a particular field within that record. Each table is composed of data imbedded in the B-tree index structure of the data base.   In order to access records using the field variables, the data base additionally includes an inverted B-tree index logically related to the original index.  The operation of the index is enhanced by the use of data compression and the use of a sparse array bit map to represent the record associated with each field.  The index structure within the data base allows each index variable to identify data by means of the index variables inde-pendently of the physical location in which the data is stored.  The efficiency of storage is further enhanced by storing the data in variable length data records.  The sparse array bit maps also be used to provide inter-record relationships for records stored in different data  tables.

Abstract: ABSTRACT            Apparatus  for  an  one-sided  or  two-sided  coating  of  a vertically travelling web comprising a coating applicator, in which said web  is  in contact with a coating substance held  at  atmospheric  pressure,  and  a  flexible  blade  co-operating  with  a  back-up  member  for  levelling  a  coating substance  layer  attached  at  the  web.  According  to  the invention,  said applicator comprises a flow regulator which forms between it and the web a clearance.  This clearance is mainly of even height or is inclined in the travel direction of the web. This height is smaller than a thickness of an eventual coating substance attached to a web without a co-operation with a regulator and the web.  The applicator is further  provided  with  means  for  arranging  a gravity controlled over-flow and a backstream substance  flux. The backstream flux is governed by the coating substance supply to the applicator,  the viscosity of coating substance,  the speed of the web travel and a slot of said applicator so that  only  a  small  amount  of  the  coating  substance  flows downwardly through this slot during normal operation of said apparatus. Said slot forms a web entrance at the bottom of the applicator.

Abstract: ABSTRACT OF THE DISCLOSURE:      For the chronologically staggered initiation of a plurality of electronic explosive delay detonators connected together with a blasting detonating machine, a signal current produced in each explosive detonator by signals sent by the blasting detonating machine, for example an impulse sequence, is integrated up in order to establish the delay time and, for carrying out of the delay, is integrated anew or integrated down to equality of the integrals or of the starting values.   According to the invention, the integrating up begins in all explosive detonators simultaneously, with the end of the integrating up being controlled by signals from the blasting detonating machine.  This end and accordingly the time period can be the same for all explosive charge detonators, while the two signal currents are possibly the same with the relative differences of the delay times being determined by the ratio of the signal currents which are different with setting and subsequent carrying out of the delay, or the end points of the integrations up or are different for each detonator.   For increasing the safety, before the setting of the delay time, an impulse sequence with determined form is sent out from the blasting detonating machine and checked in each electronic explosive detonator so that the setting of false delay values by spurious signals is avoided.   An energy storer in each explosive detonator is charged up only after successful checking of the impulse sequence at a value sufficient for initiation of the detonation.
